"The solar tulips work on a novel form of concentrated solar power (CSP). Conventional CSP uses sunlight and mirrors to focus heat on a fluid that creates steam and drives a turbine. Aora’s technology does not use a fluid. Rather, it positions its mirrors so that sunlight focuses on pressurized air in the 35-meter (115 feet) tulip tower, raising temperatures to 1,000 degrees C (1,832 F) and creating a hot pressurized gas that drives a turbine."
